April 11, 1933- M. M. ROLFSON ELECTRIC OVEN Filed March 29, 1932 Patented Apr. 1 1, 1933' UNITED s'rA'rss PATENT OFFICE ELECTRIC QVEN Application filed March. 29, 1882. Serial No. 601,794.

My invention relates to cooking devices and primarily to cooking devices that are electrically heated.

The invention is primarily comprised of a leg supported frame, so made as to adapt the same for being placed and used as upon the dining room, or the kitchen table, or any suitable supporting structure. An electrically heated oven is ada ted for being sup- 19 ported upon and within t e frame. An oven comprisesthe primary inner portion of the oven superstructure with supports disposed within the inner walls of the same for supporting a grid therein. A bafile plate is disposed transversely of the oven to cause a circulation of heated air therein. A. hot plate is disposed upon one of the primary outer surfaces of the oven structure so that the same may be turned over within the-frame and used for frying, or boiling at the same time the oven is being used. I .Electrically heated elements are provided for the heating of the oven and for independently heating the hot plates.

One of the objects of my invention consists in providing a simply constructed oven structure that is portable and that may be used with equal facility upon the dining room table, orv upon any other suitable support.

A further object of my invention consists in providing a portable oventhat may be used with equal facility for baking, boiling and frying, simultaneously.

A further object of my invention consists in so constructing the device that it is comprised of few parts and that it may be used over a relatively long period with freedom .from operating annoyances.

With these and incidental objects in view, the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forth in the appended claims, and a preferred form of embodiment of which is hereinafter shown with reference to the drawing a which accompanies and forms a part of this specification.

In the drawing:

Fig. 1 is a perspective, top plan view, of

the leg supported frame and of the oven structure shown in its normal position thereupon with the oven door open.

Fig. 2 is a sectional, side view of the mechanism illustrated in Fig. l. 5 Fig. 3 is a sectional, end view, of the mechanism illustrated in F ig. 2, the same being taken on line 3--3 of Fig. 2, looking in the direction indicated.

Fig. 4. is a front view, of the leg-supported frame and a perspective front view of the oven illustrating the oven inverted and in position for use as an oven and as a hot plate, simultaneously.

Fig. 5 is a front view, of the mechanism illustrated in Fig. 4, illustrating the same in assembled position ready for use.

Fig. 6 is an inverted plan view of a modified form of griddle element, in which two heating elements instead of one are used for supplying heat to the underside of the griddie or hot plate.

Fig. 7 is a plan view of a modified form of drip pan, shown removed from the oven.

Like reference characters refer to like parts throu hout the several views.

I prefera ly form the base frame having walls made of angle members that have a base 1, and upwardly extending side walls 2. Legs 3 downwardly extend from the bottom of the frame for supporting the same. Circular cut-outs 4 and 5 are provided in the top of the side wall members 2 in order that the electric switch terminal blocks may be made to en age therein.

n oven 6 is provided having outer walls 7 and inner walls 8 spaced apart to prdvide an air space therebetween, or to provide a space that may be filled with an insulated material 9. Supporting members 10 and 11 are disposed within the oppositely disposed walls for adjustably supportin a grid 12, or other suitable support. A be e plate 13 is disposed. transversely of the oven structure. The plate is so positioned that air passageways 14 and 15 are provided between the edges of the bafiie and the walls of the oven to thereby permit a circulation of air within the oven structure.

An electric heating element 16 is provided 100 within the oven for the heating of the oven.

- Ahot .plate 1'? is disposed upon the outside 7 the hot plate availeble for use as a griddle, or

for fr ing, or boiling, knobs Q3 and 2d are p'rovi red upon the ends of the oven, to tacili tate the easy turning of he same.

In 6 have shown griddle, or hot plate in which two heating elements 28 and 29 are dispowd thereunder, in order that i may supply heat irom independent sources to the oppositely disposed ends of the griddle, or hot plate.

In Fig. is adapted for being placed within the oven and tor-being placed adjacent and immediately below the griddle 12, so that the hot plate, or griddle, may be used for boiling or rying onthe top, and the heat from the heat ing elements 28 and 29 be adapted for having and securing the drippings from the broiling; therein.

and-engaging handles, or end supports '26 and 27 are disposed at the oppositely disposed ends of the drip I an to facilitate the same being placed at t e desired elevation within the su porting members it) and 11 While the orm of mechanism herein shown and described is admirably adapted to 'iulfili the objects primarily stated, it is to be under stood that it is not intended to confine the invention to the one form. of embodiment in various forms, all'coming within the scope of the claims which follow.

atIclaim isz 1. In a device of the class described, the

a combination of a base,'having upwardly extending side walls disposed upon the outer surface of the base, legs secured to the under side of the base, an oven adapted for being fitted to-and supported upon the base at both .its top and bottom sides; the oven being comprised of inner and outer walls spaced apart, insulation being provided therebetween; supporting members dis osed upon the inner a grid, said grid being adapted for being positioned at different points within the supports, one

a side of the oven being open, a hinged closure for the opening, a bafile spaced a art from the walls of the oven and disposed low and in s acedrelation with the grid, an' oven heating element being spaced a art from the bafile" and adapted for heating t e oven, 9. hot

late dis osed upon one side of the oven, an mdepen ent heating element for the hot plate and hand supporting and turning ill have shown a drip an 25 that knobs disposed upon the oppositely disposed ends of the oven.

2. In a device of the class described, the combination of a leg-supported base, an oven comprised of inner and outer walls space apart by an insulator, adapted for being placed upon the base and for being supports thereby on its top, or bottom surface, an electrically heated oven comprising the major portion of the structure adapted for bemg supported by the base, an opening disposed in one side of the superstructure and a hinged door adapted for maintaining the opening closed, a hot plate disposed upon the outer surface of one oi the primary sides of oven structure, an independent electriccily heated heating element adapted for heating the hot plate, and an electric switch for esch of the electric heating elements.

in a device oi the class described, the combination of a leg-supported base, a super structure ada ted for being placed upon the base and for eing supported thereby, either at its top, or bottom side, oven comprising the primary portion ofthe superstructure, a hinged door adapted to one side of the superstructure, a hot p-iate adapted to one side of the superstructure, independent electric heating eiernents for su plying heat to the oven end for heating the hot plate, and an electric switch adapted for conducting electric current into each of the heating elements.

4.. in a device of the class described, the combination of a le -supported base, a superstructure adapted or being supported upon the base and for being supported upon its top, or bottom side, hand-engaging handles disposed upon. the outer sur 'ace of the opposite ends of the superstructure, an oven disposed within the superstructure and a hot plate disposed upon the outer surface of one side of the structure, an electric heating element -for heatin the oven and for heating the hot plate, an an electric switch ada ted for conducting current through each 0 the heating elements.
